New model for this year (Do not check this option if this model was listed as new in last year's Gear Guide)The TR 63 is a trail racing shoe. It is the perfect combination of the minimal benefits of; lightweight, zero drop, terrain feedback/flexibility and non-minimal protection from rugged terrain. It is built on our Zero Impact/drop last for a natural gait and incorporates our fully flexible 270 Degree Vibram outsole that provides incredible terrain feedback plus 14 mm of EVA protection from rock and root bruising. The Dynamic Fit System secures and wraps the foot providing immediate energy transfer and a glove fit. The women's shoes are built on a last designed specifically for women's feet.
